Cutting Through the Hype

Despite the recent news that researchers successfully used the gene-editing technique known as CRISPR to modify the DNA of human embryos, the age of designer babies is not upon us, writes The Atlantic’s Ed Yong.
 
The new findings are a major scientific breakthrough, he says, because the methods used by the researchers address the problem of “mosaicism”— a pattern in which genetically edited embryos have a mix of modified and unmodified cells. However, ongoing issues around the precision and efficiency of gene editing, along with legal and cultural roadblocks, mean that such an approach will remain both limited and rare for years to come.
